The dried, sandy ground is a bit more contrasting thanks to tweaked 
textures, while using sine_wave. the used accuracy is 0.005 and 0.0005 
respectively for these two isosurfaces. In contrast, the vegetation uses 
poly_wave, a scale-dependent warp turbulence, and a still smaller 
accuracy (0.00005).
